1) A cracked or torn vacuum diaphragm in a brake power booster would
most likely cause:: a hard pedal feel requiring very high pedal effort to stop
2) to test a vacuum power brake booster in the vehicle, you should pump
the brake pedal at least 4 times, hold the brake pedal depressed, and
start the engine. the brake pedal should:: drop slightly and remain firm
3) A mechanic finds gear lube inside both rear drums on a rear wheel
drive vehicle. What is most likely the cause of this problem?: a plugged
axle 4. The rear brakes are dragging after having new linings installed
and the drums machined. the most likely cause is the:: technician use

lock-up?: master cylinder push rod adjusted too long
6) Which of the following incorrect service procedures could cause brake
pedal pulsation?: incorrect run-out on the car brake lathe
7) A common cause of pedal pulsation during brake application is:: NOT
caused by improperly torqued wheels, damaged backing plates, or lubricated
shims 9. A properly functioning load sensing proportioning valve will::
cause an increase in the hydraulic pressure during braking at the rear wheel
cylinders when the vehicle is loaded.
8) which of the following is a quick way to isolated a defective master
cylinder? There are no external leaks in the system.: pump up the brake
pedal, then hold it firm. if the pedal slowly drops to the floor, the master
cylinder may be defective.
